Improve Your Brain Health Through Resistance Training
A recent intervention study examined whether high-intensity interval training (HIIT) can improve hippocampal-dependent learning in healthy older adults. The hippocampus is central to memory formation and learning. It is also one of the brain regions most vulnerable to age-related decline.
The study investigated whether exercise intensity matters when targeting cognitive ageing.
Healthy older adults were randomised into one of three groups for six months:
Low-intensity continuous training
Medium-intensity continuous training
High-intensity interval training (HIIT)
Key findings
Only the HIIT group showed significant improvement in hippocampal-dependent learning
These improvements were maintained at 5-year follow-up
The magnitude of improvement correlated with cardiorespiratory fitness changes
Why this matters?
This study suggests that appropriately prescribed high-intensity training may meaningfully influence hippocampal function and that the effects may be durable. Particularly for individuals in their 40s, 50s and beyond, where long-term brain health becomes increasingly relevant.
